Baseline bubble inclinometers are one of the most frequently employed thoracic ROM measurement methods. However, there is currently no consensus on the accuracy and standardized procedure of their utilization.ObjectiveThe purpose of this study is to validate the accuracy of baseline bubble inclinometers in measuring the sagittal thoracic spinal ROM and to propose the standard guideline for their utilization.Method28 participants were recruited for this study. The maximum thoracic spinal ROM during flexion and extension was measured using inclinometers, with the optoelectronic motion capture system (Vicon) serving as the control group.ResultThe thoracic spinal ROM during flexion was 14.5 ± 10.5°; during extension was 19.0 ± 9.2°, and the total ROM was 33.5 ± 14.0°. The inclinometers showed moderate to high correlations with the Vicon results, particularly in measuring flexion ROM, which exhibited the highest effectiveness (r = 0.84∼0.89). The accuracy of the inclinometers was enhanced by ensuring a cervical nodding and fixation position. Additionally, it was observed that females were more suitable candidates for thoracic spinal ROM measurement using inclinometers, as they exhibited higher correlations with the Vicon results.ConclusionThis study successfully validated the accuracy of the inclinometer as a convenient thoracic spinal ROM measurement method, that can save significant time for physiotherapists in clinical settings. The measurements obtained in this study may serve as a preliminary reference for the thoracic spinal ROM in healthy individuals and standardized protocols for using the baseline bubble inclinometer.</p>","PeriodicalId":15129,"journal":{"name":"Journal of Back and Musculoskeletal Rehabilitation","volume":" ","pages":"10538127251357101"},"PeriodicalIF":1.4,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144690379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given its safety, effectiveness, and absence of side effects, acupoint therapy is being increasingly utilized in the pain management of orthopedic patients. This study conducted a network meta-analysis to compare analgesic efficacy, safety, and effectiveness of acupuncture (AP), electroacupuncture (EA), moxibustion, and acupressure, so as to provide a reference for the clinical application of acupoint therapies in managing orthopedic pain.MethodsEight databases, including PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wanfang Data, and VIP, were searched for clinical randomized controlled trials (RCTs) investigating the effects of AP, EA, moxibustion, and acupressure on orthopedic pain. The quality of the included documents was evaluated using the Cochrane Risk of Bias Tool, and graphs regarding the risk of bias and network meta-analysis were drawn by Revman 5.2, Stata 18.0 and R software (v4.3.2). Intervention ranking probabilities were quantified using SUCRA values derived from a Bayesian random-effects model.Results1) For decreasing Visual Analogue Scale (VAS) scores in patients with orthopedic pain, moxibustion therapy was identified as the optimal intervention (SUCRA=94.84%); 2) For decreasing VAS scores in patients with orthopedic pain undergoing surgical intervention, AP therapy was identified as the optimal intervention (SUCRA=76.99%); 3) For decreasing VAS scores in patients with orthopedic pain not undergoing surgical intervention, moxibustion therapy was identified as the optimal intervention (SUCRA=90.26%); 4) AP therapy (SUCRA=83.73%) demonstrated the most favorable safety profile; 5) Acupressure therapy (SUCRA=77.93%) was identified as the most effective therapeutic method.ConclusionIt is recommended to select differentiated acupoint therapies tailored to the type of orthopedic pain.

Both groups completed a six-week rehabilitation program with two sessions per week, followed by a six-week therapy-free period. Trunk range of motion, mobility-dependent pain, and perceived health were analyzed as predictors of QOL using correlation and linear regression.ResultsIncreased trunk mobility and elevated perceived health are positively associated with QOL in individuals with NSCLBP. Higher levels of mobility-dependent pain are negatively associated with QOL. The interaction between trunk mobility and changes in mobility-dependent pain intensity did not have an additional impact on QOL. Overall, our findings indicate that these associations were moderate or occasionally weak.ConclusionsTrunk mobility, mobility-dependent pain, and perceived health are relevant clinical predictors of QOL in individuals with NSCLBP. These findings highlight the importance of assessing both <u>objective</u> physical function and <u>subjective</u> pain perception when evaluating rehabilitation outcomes.
